STOVE.

Application led February 25, 1922. Serial No. 539,079.

To czZZ whom t may concern.

Be it known that I, Lun Si. CHADwroK, a citizen of the United States,residing at Shaker Heights Village, in the county of Cuyahoga and Stateof Ohio, have invented a certain new and useful Improvement in Stoves,of which the following is a full,I clear, and exact description,reference being had to the accompanying drawings.

This invention relates to improvements in the class of burners disclosedand claimed in an application liled by me on the 26th day of February,1921, and b earing Serial No. 418,111.

The burner which constitutes the subject matter of said application isso constructed that the drum or flue may be readily lifted from thecombustion device to give unobstructed access to the wick for thepurpose of cleaning` or replacing it; or the drum may be tilted withrespect to the burner for the purpose of lighting the wick. Also, thedrum or flue shown in said application has a double wall, 'the innerwall in the preferred form extending from the top about halfway down theouter wall where it joins said outer wall immediately below air inletopenings, thereby to enclose a space through which a so-called auxiliarycurrent of air mayrse. Also, provision is made for admitting fresh airto the lower end of the drum and deflecting it into close proximity tothe wall thereof. rThis arrangement prevents undue heating of the drumand at the same time increases the efficiency of the burner by adding tothe quantity of hot air which would ordinarily issue from the top of thedrum the auxiliary current of air which has during its Course of travelthrough the space between the inner and outer walls become heated byradiation from the inner wall.

My present construction possesses all the foregoing features and affordsthe same advantages as my former construction over the common types ofdrum burners wherein, as stated in said application, there is aconsiderable waste of heat and an undue heating of the drum, especiallyin the region of its upper end.

Objects peculiar to my present invention are the `provision of a burnerof the aforesaid class wherein the drum may be very readilj.v liftedfrom the burner and with equal ease re-placed thereon but which, whenplaced upon the burner, assumes a positive inge connection therewith sothat the drum may-be swung back and entirely out of the way to exposethe upper end of the burner, enabling the wick to be readily cleaned orremoved, the hinge connection incorporating a stop for limiting theswinging movement of the drum; the provision of a rest for the drum whentilted rearwardly, which rest yields under the weightof the drum andrelieves it of the shock which would otherwise be imposed upon it andwhich would be liable tocrack the enamel wherewith drums of thischaracter are usually coated; the provision of a support for the drumwhen in normal vertical position, which is independent of the hingeconnection between the drum and combustion device, thereby insuringcorrect relationship between these two units which is exceedinglyimportant in burners of this character as the slightest departuretherefrom will disturb the drafts and produce an irregular flame of lowefficiency; the provision, in a stove incorporating drum burners ofdifferent diameters but of the same height and arranged in transversealignment, a variable hinge connect-ion between the larger drum and itscombustion device enabling it to swing withinthe same vertical space asthe smaller drum; and to provide, in such variable hinge connection,means for maintaining the relatively movable parts in a definiterelation to each other during the swinging movement.

lThe foregoing objects, and others hereinafter appearing, are attainedin the embodiment of the invention illustrated in the drawingsaccompanying and forming a part hereof and wherein Fig. l is a frontelevation of a stove structure embodying my improvements; Figs. 2 and 3are sections on the respective lines Q-Z and 3--3 of Fig. l, showing thelarge and small burners, respectively; Fig. 4- is a central verticalsection from front to rear through the drum supporting collar burnerband that are incorporated in the larger burner; Fig. 5 is a plan ofwhat is shown in Fig. et, with parts broken away to more clearly revealcertain structural details; Figs. 6 and 7 are more or less diagrammaticsectional views of the hinge connection between the drum supportingcollar and burner band that are illustrated in Figs. el and 5, Fig. 6showing the parts in normal position, while Fig. 7 illustrates them inthe position assumed upon the tilting of the drum; Fig. 8 is an enlargedcentral vertical section through the smaller drum and its supportingcollar, the burner band being shown in elevation; Figs. 9 and 10 areViews, similar to Figs. 4 and 5, of the drum supporting collar andburner band of the smaller burner, Fig. 9 indicating in dotted lines themanner of applying the drum to the collar; and Figs. 11 and 12 aresectional details on the lines 11-11 and 12-12, respectively, of Fig.10.

The trame structure of the stove comprises a top 1 that is supported asuitable distance above a base 2 by end panels 3 and a bach wall e, thebase, in turn, being sustained a proper distance above the Hoor by legs5. A tuel supply pipe 10 is supported by and between the end panels 3 'acomparatively short distance above the base 2, and beyond one of theendpanels the suppi y pipe has the usual connection with' a fuel reservoir(not shown). Burners 12` and 13 are partly supported by, and havecommunicative connection with, the supply pipe through elbow fittings 14that are secured to the supply pipe by suitable clamps 15, and further,by the base 2, through legs 16. The burners are arranged in axialalignment with openings 17 in the stove top, the openings beingsurrounded by depending flanges 18.

The burner 13 is of the customary size, while the burner 12 is madeconsiderably larger to adapt it to certain purposes heretofore incapableof attainment in stoves of this character. rllhis burner produces anintense heat in a very short time as compared with the smaller burner.

Associated with the respective burners 12 and 13 are the drums or tlues2O and 21 of appropriate size. Each drum is provided with a window 22 ofmica or other suitable transparent material, and with a handle 23.

lt is essential that the drums be capable oi' ready removal trom theburners for the purpose of lighting, cleaning or removing the wicks; andit is desirable to so mount their-.that they may be conveniently liftedfrom and replaced upon the burners, or tilted with respect thereto so'as to expose the wick for cleaning, lighting and replacementpurposes,and to this end my invention provides a drum supporting collar that ishingedly connected to the burner and wherewith the drum has a readilyseparable connection, such connection serving to retain the drum on thecollar during the tilting operation while permitting the drum to heeasily and naturally lifted from the collar when the collar is in normalposition.

lt may also be explained that in burners ot, this character it isnecessary to have the drums or tlues very accurately positioned withrespect rto the burners in order to properly balance the drafts, so tospeak, and produce a clean, odorless, and etlicient llame. To this end,l provide means for supporting the collar, and, through it, the drum,from the burner independently of the hinge connection between the collarand burner, realizing that probable irregularities in the hingeconnection would result in an improper relation between the drum andburner, such provision avoiding also the accuracy in the making of thehinge parts and connections which would otherwise be required, thussaving time and labor.

To the attainment of the greatest elliciency, the tops ot the drums mustbe a certain distance below the lower edges oit the flanges 18 thatsurround the openings 17 and below which the drums are situated. lthappens that under this arrangement the small drum may swing clear ofthe flange 13 on a hinge center located to the rear or' the upper endol: the burner, while with the larger drum 2() it' is necessary toprovide a rariable hinge connection between the supporting collar whichcarries the drum and the larger burner wherewith it is associated. lshall lirst describe the hinge connection of the larger drum collar,with particular reference to Figs. 2, f1, 5, 6 and 7.

So far as they concern my present invention, the burners 12 and 13 areof the ordinary class oit tubular burners, more detailed showings otwhich mav be found in my Pat- @ma NOS. 1,246,878, 1,251,638, and.1,122,856.

A suitable distance below its upper end, the burner 12 (indicated indotted lines in Fig. 4) is provided with a circumferential bead 25. A.burner band 26 encircles the burner and has a shoulder 27 which restsupon the bead 25, and from the outer edge of the shoulder there dependsa "liange 28 that surrounds the bead and is notched at suitablecircumferentially spaced points to proride tongues 29 which are clinchedunder the bead to hold the band against vertical displacement. Extendingdownwardly and rearwardly from each side of the band 26 is an arm 30,provided with a strengthening bead 31, and which is turned inwardly atits rear end to provide an abutment 32. At points spacedcircumterentially of the band 26, lugs 35 and 36 are struck from thematerial ot the band and turned radially outwardly, those designated 35being situa-ted toward the trout ot' the burner. whilel those designated36 are located toward the rear thereof. The upper edges of the lugs and36 are in a plane parallel with the top ot the burner.

rlhe drum supporting collar is designated generally by the referencenumeral 40, and it is formed with a shoulder L11 which rests upon thelugs 35 and 3G and from the outer Ot which a skirt 41-2 depends, thecollar Leganes being positioned properly with respect to the burnerthrough the cooperation of said skirts with the outer ends of said lugs.Rising from the inner edge of the shoulder 41 and converging to within acomparatively short distance of the upperI edge of the burner is a wall43 which joins at its upper edge a gradually flaring defiector 44.Associated with the burner is the usual flame spreader 45 which serves,when the burner is in operation to direct the flame outwardly by virtueof air currents which it controls, and the iame, as it is supplied withair entering between the collar and the burner, follows the deflector 44outwardly toward the wall of the drum 20 which is supported, through itsinwardly directed flange 46, on the external ledge provided by theshoulder 41. The liange 46 has Derforations 47 for the supply ofadditional air to the drum. Cooperation of the`druirl vith the collar isidentical in both burners, and, -as illustrated in Fig. 9 (where thesmaller burner is shown), the drum is adapted to be engaged over thecollar with its bottom flange beneath a lug at the front of the collar.rlhe lug beneath which the front portion of the drum flange is engagedis designated A in both burners, and by reason of its shape and theformation of the collar, the drum is caused to automatically assume aproper position on the collar with its flange beneath the lug by merelplacing the drum over the collar.

Secured, as by spot welding or other suitable means, to the rear side ofthe skirt 42 of the collar 40 is the base of a hinge plate 50 whichcarries, at'each end, an ear 51 having an arcuate slot 52 through whicha hinge pintle 53 extends that is supported by and between the arms 30of the burner band 26. Struck inwardly from the skirt 42 of the colla-r40 are projections 55 which, when the collar is in normal position, areimmediately forward of the lugs 36 of the burner band, the projections55 being inclined downwardly and forwardly from the upper end of saidlugs for a purpose which shall presently appear'. The angle between theprojections 55 and the shoulder 41 define fulcrum points whereon thecollar is adapted to swing with respect to the burner band, the slots 52of the ears 51, as well as the rear edges of said ears which engage theabutments 32 of arms 30, being formed on arcs which have the aforesaidfulcrum points as their centers. Therefore, during the initial rearwardmovement of the drum 20, it swings upon these fulc-ruin points until itsupper end is clear of the flange 18 (note the arc whose radius isindicated by the arrow a in Fig. 2) and until the upper ends of theslots 50 engage the pint-le 53. During the further rearward movement ofthe drum, the collar 40 swings on the pintle 53, the upper end of thedrum describing an arc the radius of which is designated by the arrow bin Fig. 2. The rearward swinging movement of the collar is positivelyarrested by the engagement of stops 58, which project upwardly from theears 51, with the abutments 32; while the drum comes to rest upon ayielding flange 56 that surrounds an opening 57 in the back wall 4 ofthe stove frame, provided for the accommodation of the drum when swungrearwardly. .In this connection it may be explained that the burnerdrums are heavily coated with a vitreous enamel, and the shock absorbingquality of the yielding flange 56 protects the enamel Afrom cracking. Aswill be more appa-rent from the diagrammatic sectional views of Figs..y6 and 7, the projections 55 are so inclined that they will escape thelugs 36 when the collar swings on the pintle 53; and the engagement ofthe curved rear edges of the ears 51 with the abutments 32 preventsthecollar from sliding rearwardly on'the hinge pintle when it approaches aposition wherein the slots 52 are inclined upwardly and forwardly fromthe pintle.

I shall now describe the smaller burner, illustrated particularly inFigs. 3, 8, 9, 10, 11 and 12. To the ripper end of the burner 13 isfitted a burner band 60 which has a shoulder 61 that rests upon a bead62 of the burner. A ange 63 depends from the outer edge of the shoulder61 and embraces the bead and is notched at points spacedcircumferentially of the band to provide lugs 64 that are clinchedbeneath the bead 62 to hold the band securely in place. Immediatelyabove the shoulder 61, as well as in the region of its upper end, theband engages the burner, but intermediate these points it is enlargedsomewhat. Within the rear side of this enlargement is confined the bodyportion of the burner hinge plate 66, and the ends of this plate aredirected outwardly through slots 67 in the band and extend rearwardlyfrom the burner in parallel relation to each other, the ends of theplate being formed into hook shaped ears 63 which carry a pintle 69. Theripper edges of the plate 66, where the ends of the plate protrudethrough the slots 67 are in the same horizontal. plane as the upperedges of lugs 70 which are struck radially outwardly from the band 6()toward the front side of the burner. A shoulder 72 of the drumsupporting collar 73 bears upon the lugs 7 O and upon the aforesaidportions of t-he plate 66 adjacent theV band 60, which portions aredesignated 75 and are referred to hereinafter as collar supportingportions of the hinge plate. The design of the collar 73 is practicallyidentical with that of the former collar 40, and it comprises the skirt76 which depends from the outer edge of the shoulder 72, and theupwardly converging wall .77 which rises from the inner edge of saidshoulder and which, at its upper edge, merges into the flaring deflector78. rlhe skirt 76, cooperating with the lugs 70 and the collarsupporting portions '75 of the hinge. plate 60 (as illustrated in detailin Figs. 11 and 12) insures proper alignment of the collar with respectto the burner. A hinge plate 8O is applied to the inner rear side of theshirt 76 and terminates at its ends in parallel ears 81 which areextended through slots 82 in the skirt and lie along the inner sides ofthe upwardly directed rear ends of aforesaid ears 68, the ears 81 havingholes through which the pintle 69 extends but which holes are enoughlarger in diameter than said pintle to afford the collar the freedom ofmovement necessary to insure its being supported by the lugs 70 and thecollar supporting portion 7 5 entirely independently of the hinge.Adjacent its center, the hinge plate 8O has a downwardly and rearwardlyextending tongue which constitutes a stop 83 that is arranged to engagethe rea-r side of the burner and positively stop the collar, when thedrum 21 is tilted rearwardly and rests upon the yielding flange 85 whichsurrounds the opening 86 in the back wall l which is provided for theaccommodation of this drum.

The physical characteristics of the drums 20 and 21 are identical and Ishallproceed to describe them in connection with the sectional viewthrough the drinn 21 as it is illustrated in Fig. 8. The drum comprisesa cylindrical shell 90 which is provided atits upper end with anupwardly and inwardly extending annular wall 91 that surrounds theoutlet opening of the drum. An inwardly directed shoulder 92 is formedat about the vertical center of the drum by beading the shell inwardlythroughout its circumference, and resting upon the shoulder 92 is theoutwardly flanged lower end of an inner wall 93 which has a convergingupper end 94 disposed in close proximity to the aforesaid annular wall91. Spacers 95 centralize the upper end of the inner wall within theshell 90 and by engagement with the wall 91 retain the tianged lower endof the wall against the shoulder 92. The shell 90 is provided with aseries of air openings 96 immediately above the lower end of the innerwall. At its lower end, the shell 90 .is provided with an inwardlydirected. base liange 97 which is adapted to rest upon the drumsupporting ledere of the collar, and said base flange is provided with aseries of perforations 98.

The window 22, previously referred to, is provided by an opening 99formed in the front side of the drum a suitable distance above the topof the burner so that the flame releases may be observed therethrough,and a pane 100 of transparent material, such as mica, is secured over'the opening by a. frame 101 attached to the drum as by means of a bolt102, and a second boit which also serves to secure the handle 23 inilace.

The druin herein disclosed functions practically the saine as that shownin my former application above referred to. lhen the burner is inoperation, a certain Quantity of air enters the space between the drinnsupporting collar and the burner and it, with the air which enterstluogi the burner, under the control of the flame spreader, sup pliesthe oxygen necessary to promote con1- bustion. The burning gases followthe deflector which constitutes the upper terminal of the collaroutwardly toward the wall of the drum and are picked up by the fresh airentering through the A carried upwardlyI` the fresh air thus servingto-protect the drum against the direct heat of the tiame. However, bythe time this air has reached the lower end of the inner wall 93, ithas, by Contact and intermingling with the gases, acquired a very hightemperature. The upper portion of the shell 90 is protected from thisintense heat by the inner wall 93. The heat radiated by the inner wallcreates an upward draft within the space between said inner wall and theouter shell, and this draft is satisfied by fresh air entering` throughthe openings 96. By the time the air which enters through the opening 96(hereinbefore referred to as the auxiliary current of air) reaches thetop of the drun, it has been so raised in temperature as to materiallyincrease the eficiency of the burner by augmenting the main column ofhot gases rising through the drum.
